Graz University of Technology has developed a “green” concrete, which generates up to 30% less CO2 in the production compared to standard concrete. The secret lies in the new mixing ratio. Concrete is made up of various aggregate particles, water and binder, and includes Portland cement, which is fired at 1450°C with a great expenditure of energy. The development team, led by Joachim Juhart of the Institute for Materials Testing and Building Materials, has now changed the recipe and mixed in very fine mineral aggregate, or so-called micro-fillers, and thus reduced the amount of (energy intensive) Portland cement.
